摘要：

Allelopathy commonly exists in forest communities,it is a key factor in determining the success in construction of mixed forest.The recent decade advances in the allelopathic effect on woody plants were reviewed in this paper.The category and mechanism of allelochemicals were introduced,and allelochemicals' releasing pathways,extraction and identification were also illustrated,the main factors that influenced woody plants allelopathy were discussed.The theoretical bases and reference were supplied for forest tree ecosystem's health cultivation and recovery of its ecological function.Accordingly it was proposed to strengthen and expand the depth and breadth of research on allelopathic effects of forest trees,the research level of the mechanism of allelochemicals should be deepened to the molecular and gene dimensions,and the research objects should be expanded from the determination of the allelopathic potential from a single plant to exploring allelopathic effects of on forest community structure and species diversity.
